Environmentally hazardous draining of refrigerant is an offense punishable by law.

To prevent the entry of dampness, all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.

There is a danger of ice-up.

Refrigerant and refrigerant oil will leak out if the refrigerant circuit has not been evacuated.

Refrigerant must be extracted before opening the refrigerant circuit. If refrigerant circuit is not opened within 10 minutes after extracting, pressure may build up in refrigerant circuit by renewed evaporation. Extract refrigerant once more.

- Evacuate the refrigerant circuit using, for example, (ROB 134APF) then replace the valve - 2 -.

- Remove the valve insert - 2 - (2 ± 0.2 Nm) from the refrigerant pipe with the adapter - 4 -. Hold the valve mount - 1 - secure with a suitable tool when doing this.
